The Tennessee Coronavirus Dashboard
The sole intention of this Coronavirus dashboard is to provide a visual overview of the 2019 Novel COVID-19 as it relates to counties in Tennessee. The data is acquired from two different sources, and there are no guarantees on the accuracy of the data becaues of differences in numbers reported and reporting time.
Note: This dashboard has different graphs for small screens. For more interactive graphs, please view this website on a large screen (computer/large table).
Data
Data for “Cases across time in most populous counties” is a concatenation of the New York Times Coronavirus Data and the Tennessee State Data Center, which acquires its data from the TN Department of Health
Latest data from 05-16.
Population data acquired from the US Census.

About
================================
**The Tennessee Coronavirus Dashboard**
The sole intention of this Coronavirus dashboard is to provide a visual overview of the 2019 Novel COVID-19 as it relates to counties in Tennessee. The data is acquired from two different sources, and there are no guarantees on the accuracy of the data becaues of differences in numbers reported and reporting time.
Note: This dashboard has different graphs for small screens. For more interactive graphs, please view this website on a large screen (computer/large table).
**Data**
Data for "Cases across time in most populous counties" is a concatenation of the [New York Times Coronavirus Data](https://github.com/nytimes/covid-19-data) and the [Tennessee State Data Center](https://myutk.maps.arcgis.com/home/group.html?id=c98fc99308dd43fb98146d3cf21fc31c&q=tags%3A%22COVID-19%22&view=list&focus=files#content), which acquires its data from the [TN Department of Health](https://www.tn.gov/health/cedep/ncov.html)
Latest data from `r max(tn$date) %>% format('%m-%d')`.
Population data acquired from the [US Census](https://data.census.gov/cedsci/table?q=Tennessee%20race%20demographics&g=0400000US47&tid=ACSDP1Y2018.DP05&hidePreview=true).
